Why does the printer paper status not match the status in the network interface?

Question

Network administration

A colleague asked me to set up the MFP in LAN. I've been fighting for 2 hours now. Pereshurtil all google.
Given: kyocera FS-1035MFP printer. Lokalka with a computer and this same printer. Windows 7 PC with driver and configured web interface. Everything is connected and sees each other.
The printer does not want to print anything at all because the driver and the interface lie about the lack of paper in the tray. And everything would be simple - I already thought to correct the paper sensor - that's just the MFP itself perfectly sees the paper in the tray and scans everything wonderfully.
Tried: to reinstall the driver with different parameters. Many many times. Install with the system driver (there is no such problem with it. It simply does not print anything). Alas, nothing helped.

Answer 1

Check for errors in the printer web interface.
Restart the print service (spooler) on the computer.

Answer 2

Does it print from USB?
How about by hand?
In the driver settings, check that the default is A4

Answer 3

It is necessary to manually set the print source to cassette 2 in the print driver.
Before that, you can check - insert the paper into manual feed and send a print from the computer, if it prints, then everything is there.
